Base camp for me is a 14x16 wall tent from Davis and back packing in is a mix of a bivy and tarp or Seek outside LBO based on weather expected. Rocking a VIAM quilt at the moment but changing that in the near future.
Xtherm pad, katabatic 22deg quilt, durstan Xmid 2 solid tent (2 of us sleep in it). I did a ton of research before ending up with this setup, and I wouldn’t change a thing after 80+ nights in it.
Kifaru Tut floorless shelter, Xtherm pad, (Borah Gear bivy or MLD Duomid half nest) and a Western Mountaineering Badger 15* bag. Works perfectly for me every Sept during archery elk in CO
